Has 419 ft-lb's @4200rpm, and 377bhp@5200rpm, all from a 3.6 liter twin turbo. Car weighes in at 3650 pounds, but it does a 13.5 second quarter and 175 mph top speed.
It's a Lotus Omega, first introduced at the 1989 Geneva Auto Show and was produced in limited numbers until 1994. About 1100 Omegas were built in the years between 1991 when it entered production and 1994. Unlike other Lotus models like the Esprit, the Omega was not a homegrown model but instead a modification of someone else's work, the Opel Omega 3000GSi 24v to be precise, the top of the line Omega. At that time both Lotus and Opel were owned by GM, which felt that a special high performance model of the Omega was required to change its plain, bland image. The original engine, a 3.0L DOHC 24v inline-6, was enlarged to 3.6L, and two Garrett T25 turbos were added, along with a water-cooled intercooler ("Chargecooler" in Lotus lingo). The original 5-speed manual gearbox was substituted by a ZF 6-speed item, straight from the now-extinct Corvette ZR-1, with the deletion of the "skip-shift" feature found in the ZR-1. Apparently the gearbox was the only one GM could find that is capable of handling the Omega's massive torque. None of the Omegas are believed to exist in North America, and only 440 of the 1100 were built British-spec RHD.
Here is the Falcon XR6Turbo. It has just 321 hp, and 331 lb-ft, 3850 pounds, and a 14.0 second quarter. Boost is just 6 pounds. I think with 9 pounds of boost, it would kick the Lotus Omega's ass!
